Abstract A new retaining method for deep excavation-prestressed anchor flexible retaining method has been developed by the authors. This technique is studied by finite difference method；and the calculating results are compared with the soil-nailed support system. Critical slide zone of deep excavation is controlled by prestress values. Based on the modified bar system finite element method，the prestressed anchor flexible retaining system is calculated and analyzed through a practical engineering. The distribution rules of horizontal displacements and anchor axial force are calculated. By the numerical analysis，its advantages such as small displacements and application to super-deep excavations are investigated.
